Database error

Hi there,

I’m seeing the following issue in my debug log and the CPU usage for my site is very high.

[25-Jan-2026 03:43:27 UTC] WordPress database error You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ‘THEN 2 ELSE 6 END), wp_posts.post_date DESC LIMIT 0, 50’ at line 11 for query SELECT SQL_CALC_FOUND_ROWS wp_posts.ID FROM wp_posts WHERE 1=1 AND ( wp_posts.ID NOT IN ( SELECT object_id FROM wp_term_relationships WHERE term_taxonomy_id IN (2622,2625) ) ) AND (((wp_posts.post_title NOT LIKE ‘%flex%’) AND (wp_posts.post_excerpt NOT LIKE ‘%flex%’) AND (wp_posts.post_content NOT LIKE ‘%flex%’))) AND (wp_posts.post_password = ”) AND ((wp_posts.post_type = ‘product’ AND (wp_posts.post_status = ‘publish’))) GROUP BY wp_posts.ID ORDER BY (CASE WHEN THEN 2 ELSE 6 END), wp_posts.post_date DESC LIMIT 0, 50 made by require(‘wp-blog-header.php’), wp, WP->main, WP->query_posts, WP_Query->query, WP_Query->get_posts

According to to a search on phpmyadmin the ‘WHERE term_taxonomy_id IN (2622,2625)’ that seems to cause the issue in both errors refers to:

2603 exclude-from-search product_visibility 2622
2606 outofstock product_visibility 2625

Do I have a setting wrong?
Please let me know how I can fix this issue as it’s currently causing major issues due to CPU usage.

Thank you for your help!
